How does a wood pellet machine work?<br>
Normally, wood pellet machine can be classified right into flat die pellet machine and ring die pellet machine.



Ring die pellet mill has huge volume and high ability. It is suitable for factory use and large production. Flat die pellet mill is tiny as well as mobile. It has lower capability, suitable for home use and also small-scale production. The cost of flat die pellet mill is much less than ring die pellet mill



Structure of flat die pellet mill.

From top to bottom, a flat die pellet mill is made up of a feed receptacle, a top cupboard, a discharge outlet, a spindle box, gear box, a transmission shaft, an electric control cupboard, an electric motor, a engine base, and 4 wheels, etc.



The electric motor can be changed by a diesel motor, fuel engine, or a PTO connector.



The core components: roller and also flat die

The pelletizing part of the flat die pellet equipment is a press roller and a flat die. They are mounted in the top closet. There are 2-4 rollers mounted on the 2 ends of the roller shaft. The rollers have grooves on the surface. The roller as well as flat die is constructed from remarkable alloy steel, whose solidity is 55-60 HRC.



There are lots of holes on the flat die, whose size is from 2.5 mm to 10mm, as well as 6mm, 8mm as well as 10mm are the most common types. They realize the very best compression ratio with a great deal of experiments, ideal for greater than 30 type of materials.



The clearance between the roller as well as flat die is 0.1-0.3 mm. This is where the raw material layer kinds. There are 2 readjusting nuts on the side of the pellet mill, you can readjust the clearance to adjust to different materials.



How does a flat die pellet equipment job?

When you feed raw materials into the pellet machine with the receptacle, they fall on the flat die and also spread over it under the feature of roller.



When you start the pellet machine, the electric motor runs and bring along the main shaft via the gearbox. Journalism roller is installed on the primary shaft, so it turns around the primary shaft. At the same time, the rollers rotate around the roller shaft.



The rotating press forms solid stress and press the raw products into the holes on the flat die. The raw products get built in these holes. When they are squeezed out, they become solid cylinders. At the same time, the solid friction between roller as well as die warm up the raw materials to over 80 ° C, where the lignin as well as fibers obtain soft. They enhance the glue pressure of materials.



The diameter of the pellets is identified by the opening size of the flat die, while the length is identified by the slicer under the flat die. When the biomass pellets appear in the shape of cyndrical tubes, the slicer under the flat die reduced them right into particular size. You can adjust the placement of slicer to alter the size.




After being cut by the slicers, the pellets fall down on the pellet-throwing tray. Under the function of centrifugal force, the pellets are sent though the discharge electrical outlet.



2 kinds of flat die pellet machine

Flat die pellet mill can be classified right into roller-turned kind as well as die-turned type. The previous one has its flat die mounted on the main shaft. When the machine functions, the flat die revolves as well as the roller keep still. The later one has journalism roller installed on the major shaft. sheep feed pellet machine revolves with the main shaft, while the flat die maintain still.



Roller-turned type embraces a lot more reliable structure. It has larger capability as well as more long lasting transmission. But Die-turned type is more little as well as mobile, with reduced cost. Certainly, both of them have the ability to make top notch pellets.



Advantages and weak point of flat die pellet equipment

Apartment die pellet mill has basic framework. It is little, light and portable. The expense is much less than ring die pellet equipment It is easy to operate as well as maintain. You can observe the pelletizing procedure and also resolve any type of fault in time. So it is prominent with farmers, home individuals, as well as little fuel manufacturing plant.



The flat dies are using components, you require to change it routinely. Yet it can be used with both sides. You can transform it over when one side has actually worn out. This way you can expand their functioning life and also minimize expense.



On the other hand, the relocating range are various in the internal as well as external side of roller, which create the slide of rollers as well as abrasion on the flat die. Currently, lots of flat die pellet machine adopt tapered roller to fix this trouble. TICO flat die pellet machine embraces tapered roller and also superior alloy steel in the flat die.

Besides, the get in touch with area of roller and flat die is smaller sized than ring die pellet equipment, so the production ability and also creating price is lower.



How does a ring die pellet equipment job?

Structure of ring die pellet equipment

A ring die pellet machine is made up of a screw feeder, conditioner, roller and ring die, release port, electrical motor, transmission, pedestal.



The ring die pellet machine is driven by a direct-connected electric motor. The electric motor get in touch with the transmission via a shaft coupling. The transmission bring along the main shaft, as well as the major shaft bring along the rollers. So the roller began to revolve inside the ring die.



When you feed resources into the ring die pellet machine with the receptacle, they are sent to the conditioner, where the raw materials are blended with vapor or butter. The conditioning of the raw products intends to enhance the adhesive pressure and creating rate.



Then, the refined resources will be sent to the pelletizing closet. Under the centrifugal force, they are dispersed on the inner side of the ring die. The roller press the raw products into the holes on the ring die. coal pellet making machine and high pressure cause physical and also chemical adjustments to the raw materials.



When they are squeezed out from the ring die, they come to be solid cylindrical sticks. The sticks grow much longer, up until they are cut by the slicer outside the ring die. After that the pellets fall down as well as come out via the outlet.




2 sorts of ring die pellet equipment

According to various positionings of the ring die, there are vertical ring die pellet machine as well as horizontal ring die pellet equipment.



In the horizontal type, the ring die is placed vertically. When basic materials fall down from the conditioner, they are fed into the ring die flat by a forced feeder. In the upright kind, the ring die is placed horizontally. The feed receptacle is right over the ring die, and also the raw materials comes under the ring die straight.



In the vertical ring die pellet machine, both the roller as well as ring die turn. They form centrifugal pressure and disperse resources evenly. In the horizontal ring die pellet equipment, just the ring die rotates. The raw materials are dispersed in the ring die by the screw feeder.



Advantages as well as weakness of ring die pellet machine.

Ring die pellet mill includes high capacity. paper pellet machine manufacturing per hour is from 800kg to 20t. When it comes to flat die pellet equipment, the capability is from 100kg/h to 1t/t. So if you manufacturing demand is under 800kg, you 'd much better pick flat die pellet machine, or ring die pellet equipment is preferable.



Because of the high production, the power usage per unit is low. The abrasion in between roller and die is smaller sized. The operation as well as maintenance is very easy. The pellets are uniform in size.
